earsa'r orrics O13 CHICAGO, ILLINOIS COMBINATION CHIN BEST AND SHOULDERPAD Application filed June 27,

This invention relates to a combination chin rest and shoulder pad forattachment to a violin and has for its primary object to provide in amanner as hereinafter set forth, a device of the class above mentioned,wherein the chin rest and shoulder pad are formed from molds takendirectly from the jaw and collar bone res ectively;

A further object of the invention is to pro-- vide a chin rest andshoulder pad as aforesaid, including as a part thereof, means foradjustably clamping the chin rest and shoulder pad portions together,and for further clamping the same to a violin through the medium of thehole which is formed in violins for accommodation of the tail piecebutton.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the drawings in which like numerals are employedto designatelikeparts throughout the same,

Figure 1 is a fragmentary plan view of a violin showing an embodiment ofmy invention secured thereto,

Figure 2 is an end elevation of the same,

Figure 3 is a section taken on line 8 3 of Figure 1,

Figure 1 is a section taken on line 4L4.- of Figure 3,

Figure 5 is a section taken on line 55 of Figure 3, showing the shoulderpad in fragmentary plan,

Figure 6 is a perspective detail view of the chin rest. i

In the drawings wherein for the purpose of illustration is shown-anembodiment of my in yen-Zion, the numeral 1 designates a violin,including the usual block 2 at one end thereof, said end and block beingformed with a bore 3 for the accommodation of the usual tail piecebutton, not shown. I prefer to use the bore 3 for securing myattachment'in position, and for this purpose a clamp nut 1 issubstituted for the customary tailpiece button.

The chin rest 5 according to my invention, consists of a verticalportion 6 and an angularly ofiset, horizontally extending portion 7. Thevertically extending portion 6 is formed with a transverse groove 8,which divides the 1928. Serial No. 288,697.

portion 6 into a pair of legs 9 for seating on the upper face of theviolin. The groove 8 is adapted to receive therethrough the tail pieceof the violin not shown.- The horizontally extending portion 7 is formedwith tapered ends 10 and 11 respectively and is provided in the facethereof with a diagonally extending depression 12. That portion of thechin rest 5. which extends between the depression 12 and the end 11 iselevated above the remaining surface of the chin rest and forms a raisedroll 13 substantially triangular in contour. The chin rest 5 is formedfrom a mold taken directly from the human 1' aw, and in appliedposition, the depression 12 receives therein the jaw bone of the userand the roll 13 fits within the hollow behind and underneath the jawbone. i

The shoulder pad l l is of elongated formation and has its rearward edge15 slightly convened and its forward edge 16 slightly concaved. One end17 of the shoulder pad 14 is of substantially greater thickness than theopposite end 18, and the rearward edge 15 is of substantially greaterthickness than the forward edge 16. The lower surface 19 of the shoulderpad 14: is formed in a manner to conform to the configuration of thehuman collar bone. The shoulder pad 1 1 is of slightly less length thanthe length of the chin rest 5 and in assembled relation the end 17 ofthe shoulder pad 14: projects outwardly from the end 11 of the chin rest5.

Secured to the upper face of the shoulder pad 1 1, by means of suitableholdfast devices 20, is a clamping member 21, which is formed with areduced extension 22 which is bent upwardly and returned parallel to thehorizontal plane of the main portion of the member and spaced therefrom.Adapted for en gagement with the extension 22 is a pair of spaced barsdesignated by the numerals 23 and 12 1 respectively. In assembledrelation the bar 23 seats beneath the extension 22 and thebar 2% seatsabove said extension. relative thickness between the bars 23 and thespace between the extension 22 and member 21, and the relative thicknessof the e2:- tension 22 to the space between the bars 23 and 24: providesfor a snug fit when the several The v members are in assembled relation.The rearward edges of the bars 23 and 2a are in alignment with the rearedge of the violin, and extending rearwardly :om the bar 24 s a pair ofarms which terminate in vertial portions 26, which extend in parallelre- .ation to the end of the violin and are spaced therefrom. Theportions 26 are formed with external left hand threads for a purpose tobe hereinafter disclosed.

The rearward faces of the legs 9 of the chin rest are formed. with a.pair of bores 27, into which a pair of arms 28 are threaded. 'ihe arms28 terminate in vertically extending portions"; 29, which are disposedin oppr ing relation to the portions 26, and are med with externalright-hand threads.

"or The portions 29 and 26 are connected together by means of a pair ofinternally ihreaifled cylindrical couplings 3(.

For securing the chin rest and shoulder pad to the violin, 1 provide apin 31 which is adapted to be inserted into the bore 3 of the lolocl; 2.T he inner end of the pin 31. is ormed with a long u linal slot 32,between th opposing walls of which is pivoted a tilt key 33. The pointof pivotal connection a for the tilt hey located between the transversemedian of the tilt lrey and one end thereof. Due to its increasedlength, the end 2-35 of the tilt key 33 is heavier than the end 236 sothat the key 33 will normally swing about its pivot to assume a verticalposition. Preferably the end is thicker than the en d ill to furtherincrease the weight of the end 35. The pin 31 is formed with arearwardly extending, reduced, externally tl'n'eaded extension 37, whichprojects rearwardly from the end of the violin when the tilt key 33 is[)Uhll'lOIlQtl to lie flat against the inner face of the block 2. I

Connecting the couplings 3() 1s a concaved plate 38, each end of whichis formedwith a pair of curved lingers he inner surfaces of whichconform in contour to the outer sur faces of the couplings 30. The plateis formed with a centrally disposed perforation it) to receivetherethrough a collar ll formed on the inner end of the clamp nut l. Thecollar all is formed with internal threads for erunurement wi h theexternal threads of the *Fl ciision 37 of the pin 31. tearwardly of thecollar ll, the clamp l is formed with an annular shoulder 4-2, the innerface of which uhuts against the outer face of the plate 38.

V hen the clamp nut l is rotated to tighten the connection between thecollar 41 and the extension 37, the plate 38 is drawn towards the end ofthe violin by the action of the shoulder on the pi r and of the tilt key33 on the inner end of the block 2. Pref erably a. groove or indentation43 is formed in the inner face of the block 2 to assist in olding thetilt key 33 against rotation when clamp nut l is rotated to tighten thecon nection. The extreme end 44 of the clamp nut -l: is enlarged toequal the diameter of the shoulder 42, thereby providing a neck portion45 of reduced circumference.

To assen'ible my improved chin rest anlv shoulder pad and to secure thesame to a :lin, the arms 25 and 28 are respectively connected with theshoulder pad 14 and chin rest 5. The portions 26 and 29 of the arms 25and 28 are loosely connected together by means of the couplings 30. Theplate 258 is then positioned relative to the couplings 30, the collar llof the clamp nut 4 is inserted through the perforations 40 and looselythreaded Onto the extension 37 of the pin 31. The smaller end 36 of thetilt key is then positioned within the slot 32 and the pin 31 isinserted into the bore As soon as the end 36 clears the wall of the bore3, the abnormal weight of the end 35 of the tilt key 33 automaticallyswings the tilt key to a verti -al position. The pin is then withdrawnuntil the tilt key 33 lies flat against the inner surface of the lock 2and the clamp nut i is rotated to tighten the connection between thecollar l1 and the extension 37. After the a'ttaclnnent has thus beensecured to the violin, the chin rest 5 and shoulder pad let respectivelymay be drawn into frictional contact with the upper and lower surfacesof the violin by rotating the couplings 80. The couplings 30 areprovided with tool receiving apertures 46 for this purpose.

It is to be understood that the form of my invention herewith shown anddescribed is to be talten as the preferred example of the same and thatvarious changes in the size, shape and arrangement of parts may beresorted to *ithout departing from the spirit of the invention or thescope of the appended claim.
